A polypropylene leaflet label boasting a "fully waterproof" synthetic construction, which is also resistant to tearing and many chemicals, has been launched by the UK's Ditone Labels.
The Stay Dry Extensia is an "ultra-durable" version of Ditone's existing Extensia leaflet label developed for applications, such as use on products subject to harsh industrial conditions, where paper-based labels "cannot withstand the tough demands of their working environments". Typical market applications might include use on packs containing harsh agrochemical, cleaning and horticultural products, many of them stored outside.
